In response to Newtown shootings, some states move to put guns in classrooms

While most of the nation's students are enjoying summer break, teachers in a handful of states are studying – not their fall curriculum, but how to take out an assailant.

In Ohio, Buckeye Firearms Association, a gun rights PAC, has launched a program to educate teachers on how to take down a gunman. "We were mocked when we first said we wanted to teach this class," Jim Irvine, president of Buckeye, said. "People doubted if we could fill the class."

Yet more than 1,400 school staff members applied for the 24 spots first offered in late December, he said.

Interest in arming teachers has grown among some school staff, gun rights groups and lawmakers in the aftermath of the mass shooting at Sandy Hook Elementary School, in which 20 students – ages 6 and 7 – and six adults were killed in Newtown, Connecticut, on December 14.
